Understanding Vitamin B12 Deficiency & Injection Treatment

 

Key Information

  • The Role of B12: Vitamin B12 is essential for producing healthy red blood cells that carry oxygen around your body.
  • The Consequence of Deficiency: Without enough B12, your body produces abnormal red blood cells that do not function properly, leading to a type of anaemia.
  • Symptoms: Common symptoms include extreme tiredness, pins and needles, mouth ulcers or a sore tongue, and problems with memory or concentration.
  • Treatment Plan: Your treatment involves a course of B12 injections to restore your levels, often followed by a maintenance injection every three months.

What Happens Next?

Your treatment will involve attending the practice for your scheduled B12 injections.

It is important to attend all appointments to allow your body to rebuild its B12 stores effectively.

We will monitor your progress with follow-up blood tests to ensure your levels return to normal.
